Voltage Triton Garage Insulation

[clange]

Hi all,

This is my first time posting here and I was hoping to get some feedback on the garage insulation for a Voltage Triton RV. We live in Texas and will obviously want 3 ACs for the unit if we were to purchase it, but in looking at the brochures for this brand of toy hauler, it's not clear to me as to how well insulated the garage is. The garage will be used as a bedroom for our kids while we are camping. I'm worried that it may get too hot back there even with the third AC.

Can anyone let me know of their experience with heating or cooling the garage of a Voltage Triton?

Thanks!
